Description

【0001】
【発明の属する技術分野】
本発明は、二種以上の天然色素を同一粉体に処理して得られる改質粉体及びこれを配合した蛍光灯下でも肌色の“くすみ”を防止する化粧料に関する。
【0002】
【従来の技術】
天然色素で粉体の表面を処理してメーキャップ化粧料に利用する技術は既に公知である。しかしながら、それらは天然色素の色味のみを利用するだけに留まり、天然色素が本来持っている固有の蛍光特性(光吸収特性と光放出特性)を応用したものではない。
【0003】
【発明が解決しようとする課題】
本発明は、蛍光灯下でも肌色の“くすみ”防止力の高い改質粉体を提供する。さらに、この改質粉体を配合した“くすみ”防止効果の高い化粧料を提供することを目的としてなされたものである。
【0004】
【課題を解決するための手段】
本発明者らは、天然色素が固有の波長を持つ光を吸収して励起し、吸収した波長とは異なる波長の光を放出する特性を持っていることに着目し、天然色素の蛍光特性によって、より“くすみ”防止効果の高い化粧料を提供すべく鋭意研究を重ねた。その結果、ベニバナ赤色素とクチナシ色素を同一の粉体に処理することによって両者の蛍光特性が相乗効果を引き起こし、“くすみ”防止効果の高い改質粉体となることを見出し、この知見に基づいて本発明を完成するに至った。
すなわち、本発明は、ベニバナ赤色素及びクチナシ色素を同一の粉体に表面処理することにより得られる改質粉体及びこれを含む化粧料を提供するものである。
【0005】
【発明の実施の形態】
本発明で用いるベニバナ赤色素及びクチナシ色素で処理された改質粉体は、ベニバナ赤色素で処理した粉体をクチナシ色素で処理する方法、またはクチナシ色素で先ず処理した粉体を次にベニバナ赤色素で処理する方法、あるいはベニバナ赤色素とクチナシ色素が共存する状態で粉体を処理する方法のいずれにおいても得ることが出来るが、好ましくは以下の製造方法によって得られる。
【0006】
先ず、クチナシの果実を選別、粉砕、浸漬、煮沸、ろ過し、クチナシ色素抽出液を得る。次に、クチナシ色素抽出液に粉体を投入し、粉体にクチナシ色素を染着後、ろ過、乾燥、粉砕して「クチナシ色素パウダー」を得る。
【0007】
このクチナシ色素の抽出は、選別粉砕したクチナシの果実1重量部を2〜10重量部の水に浸漬し、30分ないし3時間程度煮沸すればよい。次に、粉体へのクチナシ色素染着は、このクチナシ色素抽出液に1〜10重量部の粉体を投入し、室温から90℃の温度で30分ないし3時間撹拌すればよい。
【0008】
ここで投入する粉体は、化粧品に使用されるものであればいずれでも良く、タルク、カオリン、マイカ、セリサイト、炭酸カルシウム、炭酸マグネシウム、無水ケイ酸、硫酸バリウム、酸化チタン、亜鉛華、魚鱗箔、オキシ塩化ビスマス、雲母チタン、酸化鉄処理雲母チタン、金属石ケン、合成高分子粉末、またはセルロース末及びシルク末等の天然物より生産される化粧品用粉体が用いられる。例えば、平均粒子径が3〜15μmの「タルク粉末」、平均粒子径が0.3〜5μmの「カオリン粉末」、平均粒子径が4〜6μmの「マイカ(別名:白雲母)粉末」、平均粒子径が3〜7μmの「セリサイト(絹雲母)粉末」、セリサイトを焼成して粉砕した「焼成セリサイト(焼成絹雲母)粉末」、平均粒径0.1〜15μmの「沈降性硫酸バリウム粉末」、板状径5〜10μmで厚さ0.1〜0.4μmの「板状硫酸バリウム粉末」、0.1μmの微細な「球状微粒子硫酸バリウム粉末」、平均粒子径が1〜40μmの「ナイロン粉末」、平均粒径が5μm前後の「真球状ナイロン微粒子粉末」、「ポリメタクリル酸エステル樹脂粉末」、平均粒子径が5〜40μmの「結晶セルロース粉末」、平均粒径が6μmから25μmの「セルロース微粉末」、酢酸セルロース粉末を加水分解することによって得られる平均粒子径が8〜10μmの「球状セルロース微粉末」、6μmから25μmの「シルク微粉末」、「再生絹フィブロイン粉末」、「多孔質絹フィブロイン粉末」、絹繊維粉末又は再生絹フィブロイン粉末あるいは多孔質絹フィブロイン粉末をN,N−ジメチルアミノエチルメタクリレート、N,N−ジエチルアミノエチルメタクリレート、N,N−ジプロピルアミノエチルメタクリレート、N,N−ジイソプロピルアミノエチルメタクリレート、N,N−ジブチルアミノエチルメタクリレート、N,N−ジイソブチルアミノエチルメタクリレートなどで変性した「絹フィブロイン粉末」などが挙げられ、これらの粉体は1種用いてもよいし、2種以上を組み合わせて用いてもよい。
【0009】
また一方で、紅花の花弁を選別、洗浄、ろ過して、アルカリ溶液に浸漬した後、ろ過してベニバナ赤色素抽出液を調製する。そして、このベニバナ赤色素抽出液に前段で得た「クチナシ色素パウダー」を投入し、pHを酸性に調製することによってベニバナ赤色素を「クチナシ色素パウダー」に重ねて染着し、ろ過、洗浄、乾燥、粉砕して本発明の改質粉体を得る。
【0010】
このベニバナ赤色素抽出液は、洗浄ろ過して得られた紅花の花弁をアルカリ溶液に30分〜1時間浸漬することによって調製することが出来る。アルカリ溶液としては、水または水と水溶性有機溶媒とを混合して、これに水酸化ナトリウム、水酸化カリウム、炭酸ナトリウム、炭酸カリウム等のアルカリ物質を0.5〜5重量%溶解した希アルカリ溶液を用いる。水と水溶性有機溶媒との混合溶液を用いるときには、水にアセトン、メチルアルコール、エチルアルコール、プロピルアルコール、その他水溶性の有機溶媒を混合して使用する。この水と水溶性有機溶媒との比率は、水10〜90重量部に対して、水溶性有機溶媒90〜10重量部が好ましい。また、前段で得られた「クチナシ色素パウダー」へのベニバナ赤色素の染着は、「クチナシ色素パウダー」をベニバナ赤色素抽出液に投入して撹拌分散し、これに塩酸、燐酸等の無機酸、ギ酸、酢酸、クエン酸、コハク酸、乳酸、リンゴ酸、酒石酸等の有機酸、もしくはこれらの酸を5〜30重量%の濃度に水で希釈または溶解したものを加えてpHを7.0以下、好ましくは3〜6に調整するればよい。
【0011】
ベニバナ赤色素及びクチナシ色素の割合については改質粉体としての特性が良く発揮できる割合が好ましく、ベニバナ赤色素1〜99%、クチナシ色素99〜1%の範囲であれば良いが、好ましくはベニバナ赤色素30〜90%、クチナシ色素10〜70%の範囲が望ましい。
【0012】
本発明に係わる改質粉体の特徴とするところは、二種以上の天然色素を同一の粉体に処理することで単独使用のときよりもより優れた“くすみ”防止効果が発現するという点にある。本発明の改質粉体における“くすみ”防止効果を具体的に説明すれば以下の通りである。
【0013】
ベニバナ赤色素は、波長350〜410nm(UV〜紫〜青)と波長500〜570nm(緑〜黄緑)の領域の光を吸収して励起し、いずれの場合も波長600±20nm(橙〜赤)の光を放出する特性を持っている。一方、クチナシ色素は、波長350〜400nm(UV〜紫〜青)の光を吸収して励起し、波長545±20nm(緑)の光を放出する特徴を持っている。
【0014】
“くすみ”防止を考えた場合、“くすみ”の原因となる「紫」から「青」及び「緑」の光を全て吸収し、580nm以上(橙〜赤)の光を放出するものが最も好ましい。
【0015】
本発明に係わる改質粉体は、同一粉体にベニバナ赤色素とクチナシ色素を処理したもので、「緑」領域の光はベニバナ赤色素が吸収して「橙〜赤」領域の光に変換し放出する。また、「紫」〜「青」領域の光はベニバナ赤色素とクチナシ色素の両者が吸収する。ここでクチナシ色素は「紫」〜「青」領域の光によって励起され波長545±20nm(緑)の光を放出するが、この光(緑)は共存しているベニバナ赤色素によって吸収される。そして、ベニバナ赤色素はクチナシ色素が放出した「緑」の光によっても励起され、この光(緑)を「橙〜赤」領域の光に変換して放出することになる。すなわち、ベニバナ赤色素とクチナシ色素が同一粉体に一体となって共存していることにより、“くすみ”の原因となる「紫」〜「青」〜「緑」領域の光は全て吸収され、更にベニバナ赤色素はクチナシ色素が励起して放出した波長545nm±20nm(緑)の光によって強く励起され相乗的に「橙〜赤」領域の光をより強く放出することになる。この相乗効果は、単一のベニバナ色素を染着したパウダーと単一のクチナシ色素を染着したパウダーを単に混合しただけでは発現しない現象である。
【0016】
更に、本発明に係わる化粧料は、この改質粉体を配合したものであって、この改質粉体を配合した化粧料を塗布するだけで蛍光灯下でも太陽光下と変わらぬ程、健康肌を呈し明るさを保つことができ“くすみ”現象を防止する。
【0017】
本発明の改質粉体は、同一粉体にベニバナ赤色素とクチナシ色素を処理したものであって、「紫」〜「青」〜「緑」領域の光を全て吸収し相乗的に「橙〜赤」領域の光に変換して放出する特性を持ち、化粧料に配合することによって顕著な“くすみ”防止効果を発現する。
【0018】
また、本発明の化粧料は、前記改質粉体を配合したものであり、その配合量は、化粧料の基本組成100重量部に対し0.01〜99重量部の範囲で選ばれ、フェースパウダー、ファンデーション、アイシャドウ、ポイントメイクアップなどとして好適に用いられる。また、本発明の化粧料の調製方法については特に制限はなく、従来化粧料の調製に慣用されている方法を用いることができる。
【0019】
【実施例】
次に、実施例により本発明をさらに詳細に説明するが、本発明はこれらの例によって限定されるものではない。
【0020】
実施例1 比較サンプルの調製
(1)サンプル1:本発明の改質粉体の製造
「クチナシ色素染着工程」
1)精製水2.5l に粉砕したクチナシの果実500g を浸漬し、3時間煮沸した後、ろ過してクチナシ色素抽出液1.5l を得た。
2)次に、クチナシ色素抽出液に平均粒子径6μmの結晶セルロース粉末500g を投入し、90℃に昇温して1時間撹拌した。その後、黄色化した結晶セルロース粉末をろ別し、55℃で乾燥し、ミキサーで粉砕してクチナシ色素パウダー495g を得た。
【0021】
「ベニバナ赤色素染着工程」
1)紅花の花弁1kgを水洗し、15l の1%炭酸ナトリウム水溶液を加え24時間放置し、ベニバナ赤色素を殆ど溶出させた。これを濾過してベニバナ赤色素のアルカリ溶液を調製した。
2)次に、このベニバナ赤色素のアルカリ溶液に前段で得たクチナシ色素パウダー495g を投入し分散させ、このアルカリ溶液のpHが5となるまで、撹拌しながら20%クエン酸水溶液を加えた。その後、濾過、水洗し、乾燥させ、ミキサーで粉砕して橙色の改質粉体(サンプル1)を485g 得た。
【0022】
(2)サンプル2:単一品「クチナシ色素パウダー」と「ベニバナ赤色素パウダー」の混合粉体
前記(1)サンプル1の「クチナシ色素染着工程」と同様にして平均粒子径6μmの結晶セルロース粉末を処理して単一品の「クチナシ色素パウダー」を得た。
次に、前記(1)サンプル1の「ベニバナ赤色素染着工程」と同様にして、クチナシ色素パウダーの代わりに、何も染着していない平均粒子径6μmの結晶セルロース粉末を処理して単一品の「ベニバナ赤色素パウダー」を得た。
そして、得られた単一品の「クチナシ色素パウダー」と「ベニバナ赤色素パウダー」を等量混合して橙色のサンプル2を調製した。
【0023】
(3)サンプル3:ベンガラと黄酸化鉄の混合サンプル
粒径0.08〜0.8μmのベンガラ3重量部に対して粒径0.08〜0.8μmの黄酸化鉄4重量部を混合して、サンプル1及び2と同色調のサンプル3を調製した。
【0024】
実施例2 三次元蛍光スペクトル測定法による改質粉体の蛍光特性評価
本発明の改質粉体(サンプル1)、本発明の改質粉体と同じ色素量をそれぞれ染着した単一品のクチナシ色素パウダーとベニバナ赤色素パウダーを混合した比較サンプル(サンプル2)、そして無機顔料のベンガラと黄酸化鉄を混合して、サンプル1及び2と同色調に調製した比較サンプル(サンプル3)の三次元蛍光スペクトルをそれぞれ測定して評価した。
【0025】
三次元蛍光スペクトル測定は、サンプルに照射する励起光の波長を少しずつ変えながら、その都度、蛍光スペクトルを測定し、照射した励起波長毎に測定された全ての蛍光スペクトルを三次元で表示して、試料の蛍光特性(光吸収特性と光放出特性)を解析する方法である。各サンプルの三次元蛍光スペクトルは、250nmから開始して600nmまで5nmずつ波長を変えながら励起光を照射し、その都度、500〜700nm領域の蛍光スペクトルを測定し三次元で表示した。
【0026】
サンプル1の三次元蛍光スペクトルを図1に、サンプル2の三次元蛍光スペクトルを図2に、サンプル3の三次元蛍光スペクトルを図3にそれぞれ示した。また、三次元蛍光スペクトルのピーク位置から計測された最大吸収波長(励起波長)と最大蛍光波長(放出波長)及び相対蛍光強度を表1に示した。
【0027】
【表1】

Figure 0004393604
【0028】
三次元蛍光スペクトルの測定結果から明らかなように、サンプル3の無機顔料はUV〜青〜緑の光を吸収していない。また、580nm以上(橙〜赤)の光も全く放出していない。一方、サンプル1とサンプル2は、いずれもUV〜青〜緑の光を吸収して580nm以上(橙〜赤)の光を放出しているが、その強さ(相対蛍光強度)は、サンプル2に比べてサンプル1の本発明に係わる改質粉体の方がより強く2.5倍以上である。
【0029】
このことから、ベニバナ赤色素とクチナシ色素を同一の粉体に処理したときの相乗効果が、単一品を混合した場合に比べ、著しく現れていることは明らかであり、「紫」〜「青」〜「緑」領域の光をより吸収して橙〜赤領域の光をより強く放出していることがわかる。
【0030】
実施例3 官能評価
次に、本発明の改質粉体をフェースパウダーに配合した処方をサンプルA、サンプルAと同じ色素量に相当するベニバナ赤色素パウダーとクチナシ色素パウダーの単品をそれぞれ配合した処方をサンプルBとし、蛍光燈下における化粧肌の明るさについ専門パネル20名による5段階官能評価を行い、20名の平均値に基づき評価した。

BACKGROUND OF THE INVENTION
The present invention relates to a modified powder obtained by processing two or more kinds of natural pigments into the same powder, and a cosmetic that prevents skin color “dullness” even under a fluorescent lamp containing the same.
[0002]
[Prior art]
Techniques for treating powder surfaces with natural pigments and using them in makeup cosmetics are already known. However, they only use the color of natural pigments, and do not apply the intrinsic fluorescence characteristics (light absorption characteristics and light emission characteristics) inherent to natural pigments.
[0003]
[Problems to be solved by the invention]
The present invention provides a modified powder having high skin color “dullness” prevention even under a fluorescent lamp. Further, the present invention has been made for the purpose of providing a cosmetic material having a high effect of preventing “dullness” in which the modified powder is blended.

It is in. The “dullness” preventing effect of the modified powder of the present invention will be specifically described as follows.
[0013]
The safflower red pigment absorbs and excites light in a wavelength range of 350 to 410 nm (UV to purple to blue) and a wavelength of 500 to 570 nm (green to yellow-green), and in each case, a wavelength of 600 ± 20 nm (orange to red). ) Emits light. On the other hand, gardenia pigments are characterized by absorbing and exciting light having a wavelength of 350 to 400 nm (UV to purple to blue) and emitting light having a wavelength of 545 ± 20 nm (green).
[0014]
When considering “dullness” prevention, it is most preferable to absorb all the light from “purple” to “blue” and “green” that causes “dullness” and emit light of 580 nm or more (orange to red). .
[0015]
The modified powder according to the present invention is obtained by treating safflower red pigment and gardenia pigment on the same powder. Light in the "green" region is absorbed by the safflower red pigment and converted to light in the "orange to red" region. And release. In addition, light in the “purple” to “blue” region is absorbed by both safflower red pigment and gardenia pigment. The gardenia pigment is excited by light in the “purple” to “blue” region and emits light having a wavelength of 545 ± 20 nm (green), but this light (green) is absorbed by the coexisting safflower red pigment. The safflower red pigment is also excited by the “green” light emitted by the gardenia pigment, and this light (green) is converted into light in the “orange to red” region and emitted. In other words, because the safflower red pigment and gardenia pigment coexist in the same powder, all the light in the “purple” to “blue” to “green” region that causes “dullness” is absorbed, Further, the safflower red dye is strongly excited by light having a wavelength of 545 nm ± 20 nm (green) excited and emitted by the gardenia dye, and synergistically emits light in the “orange to red” region. This synergistic effect is a phenomenon that does not appear by simply mixing a powder dyed with a single safflower pigment and a powder dyed with a single gardenia pigment.
[0016]
Furthermore, the cosmetic according to the present invention is a mixture of this modified powder, and even if the cosmetic containing this modified powder is simply applied, it does not change under sunlight even under fluorescent light, Presents healthy skin and maintains brightness, preventing “dull” phenomenon.
[0017]
The modified powder of the present invention is obtained by treating safflower red pigment and gardenia pigment on the same powder, and all of the light in the “purple” to “blue” to “green” region is absorbed and is synergistically “orange”. It has the property of being converted into light in the “˜red” region and released, and a remarkable “dull” prevention effect is manifested when it is added to cosmetics.
[0018]
Further, the cosmetic of the present invention is obtained by blending the modified powder, and the blending amount thereof is selected in the range of 0.01 to 99 parts by weight with respect to 100 parts by weight of the basic composition of the cosmetic. It is suitably used as powder, foundation, eye shadow, point makeup and the like. Moreover, there is no restriction | limiting in particular about the preparation method of the cosmetics of this invention, The method conventionally used for preparation of cosmetics can be used.

【Example】
EXAMPLES Next, although an Example demonstrates this invention further in detail, this invention is not limited by these examples.
[0020]
Example 1 Preparation of Comparative Sample (1) Sample 1: Production of Modified Powder of the Present Invention “Cutinia Pigment Dyeing Process”
1) 500 g of ground gardenia fruit was immersed in 2.5 l of purified water, boiled for 3 hours, and then filtered to obtain 1.5 l of gardenia pigment extract.
2) Next, 500 g of crystalline cellulose powder having an average particle size of 6 μm was added to the gardenia pigment extract, heated to 90 ° C. and stirred for 1 hour. Thereafter, the yellowed crystalline cellulose powder was separated by filtration, dried at 55 ° C., and pulverized with a mixer to obtain 495 g of gardenia pigment powder.
[0021]
"Safflower red pigmentation process"
1) 1 kg of safflower petals were washed with water, 15 l of a 1% aqueous sodium carbonate solution was added, and the mixture was left for 24 hours to elute most of the safflower red pigment. This was filtered to prepare an alkaline solution of safflower red pigment.
2) Next, 495 g of gardenia pigment powder obtained in the previous stage was added to and dispersed in the safflower red pigment alkaline solution, and a 20% aqueous citric acid solution was added with stirring until the pH of the alkaline solution reached 5. Then, it was filtered, washed with water, dried, and pulverized with a mixer to obtain 485 g of an orange modified powder (sample 1).
[0022]
(2) Sample 2: Mixed powder of single product “garden pigment powder” and “safflower red pigment powder” (1) Crystalline cellulose powder having an average particle diameter of 6 μm in the same manner as Sample 1 “garden pigment dyeing step” Was processed to obtain a single product of “gardenia pigment powder”.
Next, in the same manner as in (1) “Safflower red pigment dyeing step” in Sample 1, instead of gardenia pigment powder, a crystalline cellulose powder with an average particle size of 6 μm, which is not dyed, is treated to obtain a single powder. A dish of “safflower red pigment powder” was obtained.
Then, an equal amount of the obtained “gardenia pigment powder” and “safflower red pigment powder” were mixed to prepare an orange sample 2.
[0023]
(3) Sample 3: Mixed bengara and yellow iron oxide 4 parts by weight of yellow iron oxide having a particle size of 0.08 to 0.8 μm was mixed with 3 parts by weight of bengara having a sample particle size of 0.08 to 0.8 μm. Sample 3 having the same color tone as Samples 1 and 2 was prepared.
[0024]
Example 2 Evaluation of fluorescence characteristics of modified powder by three-dimensional fluorescence spectrum measurement method Modified powder of the present invention (Sample 1), single product garden with the same amount of dye as the modified powder of the present invention Three-dimensional comparison sample (sample 2) in which pigment powder and safflower red pigment powder are mixed, and comparison sample (sample 3) prepared in the same color tone as samples 1 and 2 by mixing inorganic pigment Bengala and yellow iron oxide Each fluorescence spectrum was measured and evaluated.
[0025]
In the three-dimensional fluorescence spectrum measurement, the fluorescence spectrum is measured each time while changing the wavelength of the excitation light irradiated to the sample little by little, and all the fluorescence spectra measured for each irradiated excitation wavelength are displayed in three dimensions. This is a method for analyzing the fluorescence characteristics (light absorption characteristics and light emission characteristics) of a sample. The three-dimensional fluorescence spectrum of each sample was irradiated with excitation light while changing the wavelength by 5 nm from 600 nm to 600 nm, and each time the fluorescence spectrum in the 500 to 700 nm region was measured and displayed in three dimensions.
[0026]
The three-dimensional fluorescence spectrum of sample 1 is shown in FIG. 1, the three-dimensional fluorescence spectrum of sample 2 is shown in FIG. 2, and the three-dimensional fluorescence spectrum of sample 3 is shown in FIG. Table 1 shows the maximum absorption wavelength (excitation wavelength), maximum fluorescence wavelength (emission wavelength), and relative fluorescence intensity measured from the peak position of the three-dimensional fluorescence spectrum.
[0027]
[Table 1]
Figure 0004393604
[0028]
As is apparent from the measurement results of the three-dimensional fluorescence spectrum, the inorganic pigment of Sample 3 does not absorb UV to blue to green light. In addition, light of 580 nm or more (orange to red) is not emitted at all. On the other hand, Sample 1 and Sample 2 both absorb UV to blue to green light and emit light of 580 nm or more (orange to red). The intensity (relative fluorescence intensity) is Compared to the above, the modified powder according to the present invention of sample 1 is stronger and 2.5 times or more.
[0029]
From this, it is clear that the synergistic effect when the safflower red pigment and gardenia pigment are processed into the same powder is remarkably exhibited as compared with the case where a single product is mixed, from `` purple '' to `` blue '' It can be seen that light in the “green” region is absorbed more and light in the orange to red region is emitted more strongly.
[0030]
